2 Claims. (Cl. 35-14) The invention aims to provide anexceptionall ly simple and inexpensive, yet an eiicient device for practicing telegraphy,'either when learning or after becoming adept, to keep in practice.

With the foregoing inview, the invention resides in the novel structure hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Figure 1 is a side elevation partly broken away and in section.

Figure 2 is a top plan View. i Figure 3 is a transverse sectional view on line 3-3 of Fig. 1.

A .preferred construction has been illustrated .l

in the `drawing and will be specifically described, with the understanding, however, that within the scope of the invention as claimed, minor variations may be made.

A base 5 is provided, said base being preferably formed from wood or plastic. Front and rear anvils 6 and 1 are rigidly` carried by the base 5 and are upwardly exposed, said anvils being preferably formed by ordinary tacks driven downwardly into said base.

Projecting upwardly from and rigidly secured to the base 5, between the front and `rear anvils 6 and 1, are two laterally spaced posts 8, and a horizontally elongated lever 9 extends `between these posts and is fulcrumed thereon. This lever is preferably formed from wood or plastic and it may be fulcrumed by providing it with a through-pin I0 having pointed ends il engaging similarly shaped recesses in `two wood or metal screws I2 threaded through the posts 8. These posts are preferably of wood or plastic with their lower ends suitably secured in sockets I3 inthe base 5.

The lever 9 carries downwardly exposed front and rear hammers I4 and I5 for cooperation with the front and rear anvils 6 and 'I respectivelyf The hammer I4 is preferably formed by the lower end of a metalrod I6 which is threaded through the frontendof the lever 9 and through upper and lower nuts `I'l and i8, the nut-|8 ,being preferably embedded in the lower side-,fof

the lever V9 while the'nut l1 is' simply` a lock'nut which can be readily loosened when it is desired to vertically adjust the rod I6 to vary the dis- The upper end of this rod IB carries a finger knob I9 for use in tilting the lever 9 in aI direction -to bring the front hammer I4 against the front anvil 6, and to tilt said lever 9 in the opposite direction, a spring isprovided. The upper end of this spring is suitably connected with 55 the lower end of a thumb screw 2| which is threaded through the lever 9 and through a nut` of nger pressure and the spring 20, the hammers I4 and i5 strike the anvils 6 and 1 and produce a clicking sound which readily simulates that produced by an ordinary sending key. Thus, regardless of theA simplicity and inexpensive nature'of the invention, it may be advantageously used in practicing telegraphy, whether the Morse code or some other code be used.

I claim:

1. A telegraphy practicing device `comprising an elongated horizontal wooden basehaving two laterally spaced upwardly open sockets between its ends and a third upwardly open socket `spaced forwardly from said two sockets, two `parallel wooden posts having their lower ends secured in` said two sockets, alined bearing screws threaded through the upper ends of` said posts, said screws having bearing sockets in their inner 1 ends, a wooden lever above said wooden base and extending between said wooden posts, said wooden lever having an integral downwardly projecting portion at its rear end, a fulcrum pin extending through said lever and having pointed` ends rockably received in said bearing sockets,

front and rear metal tacks driven downwardly into said base under the front and rear ends of said wooden lever respectively, a third metal tack driven upwardly into said downwardly projecting portion of said lever to strike said rear' tack,`a metal screw extending vertically through thefront end of said wooden lever and having a lever-operating and screw-adjusting knob at'its upper end, the `lower end of said metal screw vbeing; positioned to strike said front tack, upper and lower nuts threaded on said screw, said lower nut being embedded-in the lower edge of said wooden lever, said upper nut being a lock nut and abutting the upper edge of said 'wooden i lever, a metal spring seated in said third socket of said base, an adjusting screw extending vertically through said wooden lever and having its lower` end engaged with the `upper end of said spring,` and a nut threaded `on saidadjusting screw and embedded in the lower edge of said wooden lever.

2. A telegraphy practicing device comprising a base having front and rear anvils, a -iever fulcrumed between its ends above said base, said lever having a rear hammer positioned to strike said rear anvil, a vertical screw extending 5 its rear end.

through the front end of said -lever and having its lower end positioned to strike said front anvil,

the upper end of said screw having aiever-(mer# PoRTis P. SHAW.
